Background: This study sought to determine the optimal number of examined lymph nodes (ELNs) and examined node stations (ENSs) in patients with radiologically pure-solid non–small cell lung cancer (NSCLC) who underwent lobectomy and ipsilateral lymphadenectomy by investigating the impact of ELNs and ENSs on accurate staging and long-term survival. Materials and Methods: Data from 6 institutions in China on resected clinical stage I–II (cI–II) NSCLCs presenting as pure-solid tumors were analyzed for the impact of ELNs and ENSs on nodal upstaging, stage migration, recurrence-free survival (RFS), and overall survival (OS). Correlations between different endpoints and ELNs or ENSs were fitted with a LOWESS smoother, and the structural break points were determined by Chow test. Results: Both ELNs and ENSs were identified as independent prognostic factors for OS (ENS hazard ratio [HR], 0.690; 95% CI, 0.597–0.797; P<.001; ELN HR, 0.950; 95% CI, 0.917–0.983; P=.004) and RFS (ENS HR, 0.859; 95% CI, 0.793–0.931; P<.001; ELN HR, 0.960; 95% CI, 0.942–0.962; P<.001), which were also associated with postoperative nodal upstaging (ENS odds ratio [OR], 1.057; 95% CI, 1.002–1.187; P=.004; ELN OR, 1.186; 95% CI, 1.148–1.226; P<.001). A greater number of ELNs and ENSs correlated with a higher accuracy of nodal staging and a lower probability of stage migration. Cut-point analysis revealed an optimal cutoff of 18 LNs and 6 node stations for stage cI–II pure-solid NSCLCs, which were validated in our multi-institutional cohort. Conclusions: Extensive examination of LNs and node stations seemed crucial to predicting accurate staging and survival outcomes. A threshold of 18 LNs and 6 node stations might be considered for evaluating the quality of LN examination in patients with stage cI–II radiologically pure-solid NSCLCs.

13 Background: Early detection of lung cancer provides the best opportunity for long-term survival. In 2021 US Preventive Services Task Force (USPSTF) expanded the 2013 risk-based Low-dose CT (LDCT) screening criteria, in part to reduce unintended race and gender disparities in lung cancer detection. We evaluated the impact of the updated USPSTF criteria in a cohort of patients from an incidental lung nodule program (ILNP). Methods: We implemented an ILNP in a community healthcare system in the mid-south US. Patients with lung lesions on routinely-performed radiologic studies were triaged using evidence-based guidelines. We prospectively tracked patient demographics, clinical characteristics, procedures, complications, and health outcomes. We classified all patients in the ILNP cohort based on USPSTF 2013 and 2021 screening criteria. Statistical analysis used the chi-square test. Results: The ILNP cohort included 14,642 patients from 2015-2021. This cohort was 56% female, 65% White, 29% Black, with a median age of 64 years. Overall 1,581 (10.8%) met 2013 and 2,051 (14.0%) met 2021 USPSTF criteria. 1.9% of subjects eligible by 2013 criteria were diagnosed with lung cancer compared to 2.2% by 2021 criteria. 470 additional patients met screening criteria when we expanded from USPSTF 2013 to 2021. As expected, these patients were younger and less likely to have Medicare insurance. These additional eligible patients were significantly more likely to be female (58% v 49%, p = 0.0011) or Black (28% vs. 18%, p < 0.0001) compared to those eligible by 2013 criteria. 44 of the 470 (9%) were diagnosed with cancer: 36% adenocarcinoma, 18% squamous, and 11% small cell, 11% non-lung primary, 9% non-small cell lung cancer NOS, and 15% other or unknown histology. The median tumor size was 3 cm with an interquartile range from 1.7 to 4.2 cm. The clinical stage distribution was 34% I, 4.5% II, 15.9% III, and 31.8% IV. Conclusions: In this selective community-based cohort, USPSTF 2021 criteria identified a higher percentage of subjects with lung cancer and were more inclusive of women and minorities compared to USPSTF 2013 criteria.

Abstract Objective The aim of this study was to determine the outcomes of patients with T3N3 esophageal cancers and determine differences between the clinical stage and pathological stage. Background Locally advanced esophageal cancer is associated with poor long-term survival. Pre-treatment and post-treatment stage may differ due to the effect of neoadjuvant therapy and inaccuracies in staging. Multimodality staging followed by discussion at an MDT is considered the gold standard. Despite this, patients can be under-staged or over-staged leading to inadequate or unnecessary treatment associated with high levels of morbidity. Methods Consecutive patients from a single unit between 2010 - 2018 were included with either clinical (cT3N3) or pathological (pT3N3) esophageal cancer. Outcomes were compared between patients that underwent transthoracic esophagectomy and radical two field lymphadenectomy with or without neoadjuvant treatment and those patients staged cT3N3 treated non-surgically (NSR). Demographics, clinical and pathological stage, histological information and outcomes were recorded. Patients were staged using the TNM 8. Results This study included 156 patients, of which 63 had non-surgical treatment, only 3 of these had radical treatment. Of the remaining 93 patients who underwent esophagectomy, 34 were cT3N3, 54 were pT3N3 and five were unchanged before and after treatment. Median overall survival (OS) for surgical cT3N3 patients was significantly longer than pT3N3 and NSR (median: NR vs 19 vs 8 months, p<0.001). Twenty-seven patients with cT3N3 had lower staging following treatment whilst 3 had a higher stage. Conclusion T3N3 disease carries a poor prognosis. Within this cohort cT3N3 disease treated surgically has a high 5-year overall survival suggesting possible over-staging and stage migration due to neoadjuvant therapy. To contrast this those not having surgery have a dismal prognosis. The impact of neoadjuvant treatment cannot be predicted and, current staging modalities may be inaccurate. Clinical stage should be used with caution when counselling patients regarding management and prognosis.

302 Background: The preoperative stage and intraoperative stage of gastric cancer were unified as the clinical stage in the 8th edition of the TNM classification (UICC). Although there are some reports about the relationship between preoperative stage and prognosis, the relationship between intraoperative stage and prognosis remains unclear. The aim of this study was to clarify the impact of intraoperative diagnosis and staging on long-term survival. Methods: Overall survivals were examined in 915 patients who underwent curative resection for gastric adenocarcinoma between April 2011 and March 2019 in our hospital. Results: The median age of the patients was 69 years (27-90 years), including 585 male and 330 female. The median follow-up period was 33.6 months (0.1-86.7 months). The number of the patients according to intraoperative stage were 641(70.1 %) in stageI, 15(1.6%) in stageIIA, 135(14.8%) in stageIIB, 111(12.1%) in stageIII, 12(1.3%) in stageIVA and 1(0.1%) in stageIVB. The hazard ratios of intraoperative stage for overall survival were as follows (ref: StageI); StageIIA, 6.990 (95% CI: 2.473-19.760, p < 0.001), StageIIB, 2.234 (95% CI: 1.220-4.092, p = 0.009), StageIII, 4.091 (95% CI: 2.416-6.928, p < 0.001), StageIVA, 6.061 (95% CI: 2.150-17.080, p < 0.001), StageIVB, 14.92 (95% CI: 2.035-109.3, p = 0.008). Conclusions: The survival of intraoperative StageIIA was poorer than StageIIB/III. Intraoperative positive lymph node metastasis could be negative impact of survival, even if tumor invasion was T1 or T2.
